run() function optional parameters create typescript error

[plumpNation]

the axe.d.ts file has three optional parameters, however, the run function handles internally providing the callback on it's own.

axe.run(callback);

The recommended approaches I have found say use undefined for the optionals, however this causes issues with normalizeRunParams() that determines which parameter you are passing in.

I suggest adding overloads to the axe.d.ts file to solve this.
